Clearly your only giving 5 points but ok.

Answer:     Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Buy less plastic and bring a reusable shopping bag. Use long-lasting light bulbs. Energy efficient light bulbs reduce greenhouse gas emissions. Also flip the light switch off when you leave the room!

What food chain is represented in the above food web?
fenix001 [56]
<span>B- tree > insect > frog> snake> hawk

The food chains are represented by organisms interconnected by red arrows that point in the direction of the one that's eating. So, the relation that is explicit by the arrow is that the organism from where the arrow departs is eaten by the organism where the arrow is pointing towards to. So, the food chain that can be observed accurately in the food web is: the tree is eaten by the insect, the insect is eaten by the frog, the frog is eaten by the snake, and the snake is eaten by the hawk.

Why are telomeres problematic for eukaryotic chromosome replication? a) They are highly repetitive and thus hard to replicate co
Natalka [10]

Answer: Option E

Maintaining very long telomeres promotes cancer cell formation.

Explanation:

Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.

Usually, in eukaryote chromosome replication, telomeres are not replicated.

Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.

The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres

Chargaff's rule states that the amounts of guanine and cytosine are roughly the same, and the amounts of adenine and thymine are
Mazyrski [523]

Answer:

True.

Explanation:

The Chargaff's rules indicate that in the DNA of all living organisms the amount of adenine (A) should be equal to the amount of thymine (T), while the amount of guanine (G) should be equal to the amount of cytosine (C). These rules were useful to describe the structure of  the double helix and also enable to describe base patterns that often are associated with specific gene regions (for example, promoter regions are rich in AT). Moreover, an imbalance in the 1:1 equilibrium ratio is associated with mutations that may cause diseases such as cancer.
